Domestica the important components of RNA utilized were purine bases, adenine and guanine (Brookes and Fraenkel, 1958). In C. homivorax a mixture of adenine, cytosine, and guanine could replace RNA (Gingrich, 1964). However, in A. housei larvae RNA and DNA were utilized almost equally well; but only the nucleotides adenylic acid, guanylic acid, cytidylic acid, and uridylic acid irrespective of their purine or pyrimidine base (House, 1964). 05% decreased the number of adults produced (House and Barlow, 1957).
